Hi! I am Sonny. I'm a Skyline Photographer I love music and travel! Love travel with my Nikon

Visit my creative jobs

I am city skyline and landscape photographer. I fell in love with photography when I bought my first digital camera Canon 5d Mark II back in 2011. I love to travel and discover cities and landscapes through the lens of my camera. I am always exited about history of our civilization and I am trying to show historical depth and unity of ancient and modern cultural layers in my urban photos.

Roasting coffee transforms the chemical and physical properties of green coffee beans into roasted coffee products. The roasting process is what produces the characteristic flavor of coffee by causing the green coffee beans to change in taste.

Unroasted beans contain similar if not higher levels of acids, protein, sugars, and caffeine as those that have been roasted, but lack the taste of roasted coffee beans due to the Maillard and other chemical reactions that occur during roasting.

The majority of coffee is roasted on a large scale, but small-scale roasting has grown with the trend toward specialty shops.

 Equipment

The most common roasting machines are of two basic types: drum and hot-air, although there are others including packed-bed, tangential and centrifugal roasters. Roasters can operate in either batch or continuous modes. Home roasters are also available.
